Worth mentioning the Google Kythe project [0] which is designed around the idea of providing a graph of entities appearing in the code to build tools which work with code. I always thought that it would be good if the Google Kythe and the Language server protocol projects could merge, i.e. if the Language server protocol could expose a Kythe-like graph to editors. This seems to be along the lines of what OP suggests. [0] https://kythe.io/ https://kythe.io/
